.TRAVELING OILER.

SPECIFICATION forming part of Letters Patent No. 649,027, dated May 8,1900.

Application filed April 22, 1899. Serial No 714,001. (No model.)

T to whom it may concern:

Be it known that I, JAMES H. WOODARD, a citizen of the United States,and a resident of Dayton, Campbell county, State of Kentucky,

have invented a certain new and useful Traveling Oiler and I do declarethat the following is a clear, full, and exact description of theinvention, such as will enable others skilled in the art towhich itappertains to make and use the same, attention being called to theaccompanying drawings, with the reference-numerals marked thereon, whichform a part of this specification.

The object of this invention is to provide an oiler to apply lubricantto the wearingsurfaces of machine parts while such parts are in motionand where such surfaces are not readily accessible either on account oflocation or on account of the motion of the parts to which they belongor on account of both causes combined. It is principally designed foruse in connection with elevator machinery to lubricate the interiorwearingsurfaces of the pressure-cylinder where such is used. It is quitedifficult to apply oil to the inside of such cylinder, since it must bedone while the moving head is farthest inside, for which purpose a swabat the end of a rod or pole is used. The objection to this man- 0 ner ofoiling is that the work to be done can not be seen, for which reason itis often done imperfectly either by insufficient application of thelubricant or by an excessive one, causing waste of the same.

3 5 My invention consists of a device constructed in a certain manner,as set forth in the following specification and particularly pointed outin the claim at the end thereof, the whole containing a full descriptionof my 0 invention, together with its operation, parts,

and construction, which latter is also illustrated in the accompanyingdrawings, in which- Figure 1 shows in a longitudinal section thecustomary pressure-cylinder of a hydraulic elevator, the same beingfitted out with my traveling oiler. Fig. 2 is a cross-section of Fig. 1.Fig. 3 is an enlarged longitudinal section of the ejecting device.

Fig. 4 shows my invention applied to an elevator-cab, the latter beingshown in top view. Fig. 5 shows a part of the cab in side view.

In Figs. 1 and 2 of the drawings, 8 indicates the pressure-cylinder of ahydraulically-0perated elevator. 9 is the piston-head, and 10 travelingsheaves, of which there are a number mounted side by side in a bearing11, which is supported on a track 12. Bearing 11 is connected to head 9by means of a piston-rod 13 for the purposeof moving the former, withsheaves 10, alternately in opposite directions. 14 is part of thehoisting rope or cable, which passes repeatedly around the sheaves, ofwhich there is also a stationary set 10, the other part of such ropepassing up the elevator-shaft, where it finally connects to the cabtherein. By admitting water to the cylinder back of head 9 the latter iscaused to move out, whereby the distance between the traveling andstationary sheaves is increased, taking up a correspondingly-increasedamount of rope, which comes from the part within the elevator-shaft,with the ultimate effect of lifting the cab. The reverse takes place bypermitting the water to discharge from cylinder 8. Lubrication of theinterior of this latter is rather difficult, since it must be done whenthe piston-head is farthest inside, at which time the distance from theopen end of the cylinder, where ac- 8o cess may be had, to the pointwhere the 111- bricant is to be applied is seldom less than ten feet.

My improved lubricating device contemplates, first, a discharge-pipe 15,shaped on a circle parallel to the interior of the cylinder, but ofsmaller diameter, so as not to touch this latter. It is provided with anumber of ejecting-orifices 16, disposed so as to discharge against theinside surface of the cylinder, and 0 may be supported in any suitablemanner as, for instance, by braces 17, projecting from a clamp18-whereby this device is attached to thepiston-head or, as shown, tothe piston-rodl3. Inahorizontalcyliuder, as shown, it is not necessarythat pipe 15 follow all around the interior of the cylinder, and alimited discharge against the upper part of the surface only issufficient, since the oil readily flows down and covers also the lowerpart. On the outside-that is, in a position never obstructed by thecylinder or any other part and in a position so as to be always readilyaccessiblethere is an ejecting device 19, secured in position in anysuitable manner as, for instance, by attachment to hearing 11. Thisejecting device is substantially a forcepump consisting of a cylinder21, adapted to contain lubricant, a plunger 22, and an operating-rod 23,provided with a convenient handle. This ejecting device is connected tothe discharge-pipe 15 by a conduit in shape of a pipe 24, which conveysthe oil from the former to the latter. The operation is now readilyunderstood, and if lubrication is desired it is only necessary to expelthe oil in front of plunger 22 by pushing the latter toward thedischarge end of cylinder 21. This can be done conveniently at any time,and particularly when head 9 is farthest within cylinder 8. The oil issupplied to the ejecting device from an oil-reservoir 25, mounted aboveit, and the supply from which is controlled by a suitable cut-offdevice. Such supply proceeds automatically, for which purpose reservoir25 is connected with cylinder 2]. back of plunger 22, and this latter isprovided with a spring-actuated valve 26, seated therein and openingoutwardly. A spring 27 is provided around rod 23 of theoperating-handle, whereby after ejection the parts are restored tooperative position, in which condition they normally remain. l/Vith thisautomatic oilsupply added the operation of the parts is now as follows:When. the plunger is pushed outwardly to discharge the contents ofcylinder 21, oil from reservoir 25 follows, filling the space back ofthe plunger. \Vhen the latter is returned to its normal position byspring 27, valve 26 opens, permitting the oil to pass to the other sidein front of the plunger. Return of oil during this movement to reservoir25 is prevented by an interposed checkvalve 28. Valve 26 closes as soonas plunger 22 comes to a rest, thereby preventing further discharge fromreservoir 25. With this arrangement it is now only necessary whenlubrication is desired to give operating-rod 23 a push, which not onlyeffects discharge of the oil, but also provides for a return of theparts to an operative position with a fresh charge in readiness forsubsequent use.

In Figs. 4 and 5 my device is shown as applied to an elevator-cab tolubricate the slides and the guides of the runway in the shaft. 29indicates these latter, and the ejecting device 21 and reservoir 25 arelocated on top 31 of the cab. Discharge-pipe 15 is shaped, as shown, tosurround the three sides of guides 29. The handle of the ejecting devicemaybe readily operated either directly or by means of a suitableintervenient construction. To obtain a thorough and uniform distributionof the oil over the surfaces to be lubricated, I provide absorptiveretainers 32 below the discharge-pipes in each case. For cylinder 8 itconsists of part of a ring, completing the circle of which pipe 15 formsthe other part. In case of guides 29 it consists of a depending bracketor frame shaped like the discharge-pipe above it and surrounding theguides. In both cases these parts are covered or wrapped with absorptivem aterial,like felt or cotton-waste, to a thickness sufficient to causethis material to come in contact with the surfaces to be lubricated.These retainers retard the oil and prevent the same from running at onceoff from the surfaces to be lubricated and move it repeatedly over them.

Having described my invention, what I desire to protect by LettersPatent is as follows:

A traveling lubricating device for oiling the interior of a horizontalcylinder, being shaped to conform substantially to the interior shapeand size thereof, its upper part, opposite the upper part of theinterior surface of the cylinder, consisting of an oil-discharge pipe,substantially semicircular and provided with ejecting-orifices, directedagainst the cylinder and its lower part, opposite the lower part of theinterior surface of the cylinder, forming an absorptive oil-retainer,also semicircular and being in contact with such lower surface, servingto distribute over the latter the oil discharged against the upper partof the surface, a source of oil-supply and an oilconduit connecting itwith the oil-discharge pipe, the whole secured close to the outer sideof the piston of the cylinder and traveling therewith.

In testimony whereof I hereunto set my signature in presence of twowitnesses.
